1. Dapoxetine:
2. RH-5849: RH-5849 is moderately toxic and inhibits feeding, accelerates molting and reduces egg laying for scale, sheath and dipteran insect larvae. It is mainly stomach poison, which is effective 2-3 days after application and has a long lasting effect. It is suitable for the prevention and control of vegetable cabbage loopers, Spodoptera litura and Plutella xylostella, rice leaf rollers and armyworms.
3. Tebufenozide:
4. Methoxyfenozide:
5. Chromafenozide: After being ingested by insects, Chromafenozide inhibits insect feeding within a few hours and causes insects to molt early and die. Chromafenozide has strong insecticidal activity against noctuids and other caterpillars, regardless of the period. The main dosage forms are 5% chromafenozide suspension, 5% chromafenozide emulsion and 0.3% chromafenozide powder. It is suitable for preventing and controlling lepidopteran pest larvae on vegetables, tea trees, fruit trees, ornamental plants and rice crops. To prevent and control onion armyworm, spray with 1000 times diluted 5% chromafenozide suspension. To control beet armyworms, spray 5% chromafenozide suspension at a dilution of 1000-2000 times.
6. Tebufenozide:
7. Pyriproxyfen:
8. Cyromazine: Cyromazine is a low-toxic insecticide of the insect growth regulator class. It has very strong selectivity and is mainly active against Diptera insects. Its mechanism of action is to cause morphological deformation of Diptera insect larvae and pupae, and incomplete or inhibited adult emergence. The drug has contact and stomach poison effects, strong systemic conductivity, a long lasting effect, but a slow action rate. Cyromazine can be mixed with abamectin, chlorpyrifos, and insecticide to produce compound insecticides. Cyromazine is suitable for a variety of fruits and vegetables, and has a good insecticidal effect on "fly" pests. At present, it is mainly used in the production of fruits and vegetables to prevent and control: American leafminers, South American leafminers, bean stem black leafminers, onion leafminers, trifoliate leafminers and other leafminers in various fruits, solanaceous fruits, beans and various leafy vegetables, and root maggots (leek late eye fungus mosquitoes) in leeks, onions, and garlic.
